Secure a Premium 13 Number for Your Brand
13 numbers are Australia’s most memorable business phone numbers. Short, powerful and highly sought after, they help brands dominate national advertising.
What Is a 13 Number?
A 13 number is a six-digit national business phone number that provides a short, highly memorable contact point across Australia.
Unlike 1300 or 1800 numbers, 13 numbers are shorter and more exclusive, making them powerful branding assets for established businesses.
Because supply is limited, 13 numbers are tightly controlled and often associated with large brands and national advertising campaigns.
Why Businesses Choose 13 Numbers
Ultra Memorable
Only six digits, making them easier to recall across radio, TV and outdoor advertising.
Premium Brand Positioning
Signals scale, credibility and national presence.
Limited Availability
Operate Australia-wide without geographic restrictions.
National Reach
Operate Australia-wide without geographic restrictions.
Maximum Marketing Impact
Ideal for large campaigns where recall drives inbound enquiries.
Turn your 13 number into a phoneword
A 13 phoneword combines the shortest business number format with a memorable brand or service name.
Because only four letters are required, 13 phonewords create extremely powerful branding opportunities.
The shorter the number, the stronger the recall.
Flexi Dial provides access to premium 13 phonewords designed for national campaigns and established brands.

Phone Numbers (1300, 1800 & 13)
What is the difference between a 1300, 1800 and 13 number?
A 1300 number is a 10-digit national number where callers pay a low shared cost. A 1800 number is a 10-digit toll-free number where the business covers the call cost. A 13 number is a short, 6-digit premium number with limited availability and a fixed caller charge.
What is a phoneword?
A phoneword is a business number that spells a word using the letters on a phone keypad. For example, 1300 PLUMBER (1300 758 623). Phonewords are proven to be five times more memorable than digit-only numbers.
How much does a phone number cost?
Costs vary depending on the number type and its memorability. Premium phonewords and 13 numbers may attract higher allocation charges. Contact our team for a tailored quote.
Can I choose a specific number or phoneword?
Yes. You can search for a specific number or word using our search tool.
What is overdial?
Overdial refers to extra characters beyond the standard digit length of a phone number. For example, 1300 PLUMBER has seven letters but only six digits are required after the prefix. While overdial works on most networks, some VoIP systems may not support it. We recommend displaying your numerical number alongside your phoneword.
Can I port my existing 1300, 1800 or 13 number to Flexi Dial?
Yes. We can assist with porting your existing number. The process is straightforward and professionally managed.
Can I route calls to a mobile phone?
Yes. Calls to any 13, 1300 or 1800 number can be routed to mobiles, landlines, offices or call centres.
Are these numbers available Australia-wide?
Yes. All 13, 1300 and 1800 numbers provide national coverage across Australia.
What happens if my number isn't connected to a service?
If your number is not connected to an active phone service, your rights of use remain valid for three years from the last active service date. After that, the number may become available for reallocation.
Inbound Call Plans
What is an inbound call plan?
An inbound call plan is the service that activates and routes your 13, 1300 or 1800 number. It determines how calls are handled, where they are directed, and what features are available.
What features are included?
Depending on your plan, features may include smart call routing, IVR menus, call queuing, time-based routing, voicemail-to-email, call whisper, missed call alerts, real-time reporting and analytics.
Can I change my call plan later?

Do I get access to a management portal?
Yes. All call plans include access to our self-service management portal where you can adjust routing, review analytics and manage your numbers.
AI Voice Agents
What is an AI voice agent?
An AI voice agent is an intelligent automated system that answers inbound calls using natural, conversational language. It can understand caller intent, capture details, categorise enquiries and route calls to the appropriate person or department.
Does AI replace my team?
No. AI handles overflow, after-hours calls and repetitive enquiries. Urgent or complex calls are escalated to your team instantly.
Does it work with my existing number?
Yes. AI voice agents integrate directly with your 13, 1300 or 1800 number and your existing inbound call plan.
Can it send notifications when a call is handled?
Yes. SMS and email alerts are sent immediately with caller details and an enquiry summary.

Yes. AI voice agents can be configured to send captured data directly into your CRM system.
Does it support multiple languages?
Yes, AI voice agents support multilingual capabilities, allowing them to communicate with customers in multiple languages seamlessly.
Hosted Phone Systems & Voice
What is a hosted phone system?
A hosted phone system (also known as cloud PBX or VoIP) allows your business to manage calls over the internet rather than traditional landlines. There is no on-site hardware required.
Do I need to buy hardware?
Not necessarily. Hosted phone systems work with softphones, mobile apps and browser-based calling. Desk phones are optional and can be provisioned if required.
Can remote staff use the system?
Yes. Your team can make and receive calls from any location with an internet connection — office, home or on-site.
Does it work with my existing 1300 or 1800 number?
Yes. Your existing numbers integrate directly into the hosted system.
What happens if the internet goes down?
Calls are automatically routed to mobile numbers or alternative destinations as a failover. Cloud-hosted means no single point of failure.
What is SIP trunking?
SIP trunking connects your existing on-premises PBX or phone system to our network, providing reliable and cost-effective calling without replacing your current hardware.
What features are included?
Core features include auto-attendant (IVR), call forwarding and routing, voicemail-to-email, call recording, call analytics and reporting, multi-site support and mobile app integration.
SMS

Yes. Messages can be personalised with customer data fields and branded with your business sender ID.
